PAPER-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 264,972, datedSeptember 426, 1882.

Application filed March 5, 1881.

To all whom it may concern Be it known that I, CHARLEsE. ToRRANcE, ofHolyoke, in the county of Hampden and State of Massachusetts, haveinvented a new and useful Improvement in Paper Cutting Machinery; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, referencebeing had to the accompanying drawings,making a part of this speci tication, and to the letters and gures ofreference marked thereon.`

The object of my invention is to cut all the sheets of paper from acontinuous web or strip as it passes from the paper machine in beingmanufactured of a uniform size, and I accomplish this by the apparatussubstantiallyT hereinafter described, and illustrated in theaccompanying drawings, in which- Figure I is a front view of apaper-cutting machine made according to my invention, with the smallrolls, fixed stop-bar, and the fixed cutter broken away. Fig. II is avertical transverse section of the machine at line I of Fig. I. Fig. IIIis a plan view of one modification of thc take-up frame and roll, or asufficient portion thereof to show its construction. Fig. IV is avertical section of the same at line E of Fig. III. Fig. V is an insideview ofthe cam which actuates the movable knife in cutting the sheetfrom the web. Fig. VI is a transverse vertical section of the same atline F, and Fig. VII is another modification of the take-up mechanism.

ards of convenient size and form to furnish a support and bearings inwhich thejournals or ends of the shafts and drums of the machine mayrevolve.

l and 2 denote the two main rolls, which receive the continuous web ofpaper from the machine as fast as it is manufactured, the said web beingsuspended from between said receiving-rolls, as shown by the dottedline,down in front of the roll, as 5, and movable stopbar, as S, and betweenthe feed-rolls, as 10, and the knives or cutters, as 13 and Vlet.

Below the roll, as 1, a frame, 3, provided with a small roll, as 5, inits front end, is arranged, preferably at such an inclination andresting upon small rollers, c c, if desired, that v (Model.)

its own weight will cause it to slide forward when left free. y

Below the roll, as 5,and a little forward of it, I arrange a curved orinclined shelf or frame, preferably supplied with small. rolls, asV 6,(which in Fig. I are partially broken away to show the movable stop-barmore clearly,) as shown in Fig. II, with a fixed bar as 9, at the loweredge of said shelf or frame; and a lmovable stop-bar, as 8,1conn`ectedat each end to a bar, as 7,is arranged to have a slight movement towardand from the bar 9 by means ot' a pivoted lever, as 11, one end of whichis oonnected with the bar 7, and whose opposite end engages in agroove,as 24, on the inside of the cam-disk, as 17, secured on a shaft, as 21.

In the modification shown in Fig. 1I, I arrange two rolls, as 10, torevolve in close proximity to each other, and these rolls are madeadjustable toward and from each other by means of adj Listing-screws, ass, and below these rolls a lixed knife', as 13, is bolted to the frame,with another movable knife, as 14, preferably attached at its ends todisks, as a, one pivoted in each end of the frame.

A cone-drum, as B, is arranged to revolve in bearings in theframe, fromwhich a belt cxtends around a similar cone-drum, as 16, above, and thelatter is geared to the cam-shaft, as 2l, also arranged to revolve inthe frame.

rlhe disk, as 17, has a cam-groove, as 23, made in one side, as shown inFigsVand VI, in which moves a roll hung in the side of the bar, as 18,which bar is pivoted at one end to the knife-disk a, and is forked atthe other end to stride and be supported by thejonrnal or shaft, as 21.A cam-groove, as 24,is made in the other side of the disk 17, in whichmoves a'roll hung o n the lower end of the lever 11, pivoted to theframe at 12, and delivery-rolls, as 19 and 20, are hung in the frame,around which bands or tapes, asm, extend, and these rolls are moved byaband from a .pulley on the lower cone-shaft, as B. These concs ordrums, as 16 and B, are reversed in their reln-' tive position with eachother that is to say, the small end of one is over the large end of theother-and a belt extends around both, whereby, the upper one beingdriven from the lower one, the speed of the former may be varied bymoving the belt along the cones.

The operation of the invention `is as follows:

IOO

Power being applied to revolve the cone B by a drivin g-'belt aroundapulley connected therewith, the receiving-rolls 1 and 2 are made torevolve by a beltfrom a pulley from the coneshaft below, and the web ofpaper from the paper-machine, passing between the rolls 1 and 2, is madeto movedown in front of the roll 5 between the stop-bar S and the bar 9and between the iiXed knife 13and the movable knife 14, as shown indotted line in Fig. II. As the cone 16 and the disk 17 revolve the cam24 moves the lower end of the pivoted lever 11 outward and moves in itsupper end, moving the stop S in against the web of paper and clamping itbetween the stop 8 and the bar 9 and stopping the web in its downwardmovement. At the instant the web is stopped the cam 23 in the oppositeside of the disk 17 forces the arm, as 1S, backward, moving the disks aon their pivots and causing the knife 14 to move past and against theknife 13, and cutting a sheet from the web. Of course thereceiving-rolls, as 1 and 2, cont-inne to deliver the web of paper afterit is stopped in its downward movement by the stop-bar 8 below, and assoon as this stoppage takes place the tension ofthe web againstthe roll5 and frame 3 ceases, and thelatteris free to move forward against theweb of paper still being delivered from the rolls land 2, moving the webwith` it, and this movement of the frame 3 and its roll 5 against theweb continues while `the knives are making the cut, as described. Assoon as the cut is finished, however, the cam 24 moves the stop 8 awayfrom its position against the paper, and the feed-rolls, as 10, whichrevolve againstthe webof paper, draw the latter downward again, andinthusbeingdrawn down the tension of the web against the roll Sandframe3 is renewed and overcomes the weight ot' the frame 3 and moves thelatter back into place. The feed-rolls, as 10, arranged as shown inFigs. I and Il, are adjusted by the adjustingscrews, as s, to constantlyrevolve against the web of paper, passing from the receiving-rolls 1 and2 with just the desired degree of friction, so that when the web ofpaper is held stationary by the stop-bar 8 and bar 9 said rolls 10 will'slip against the paper as they revolve, and when the paper is releasedthe friction of the rolls against the paper will be just sufficient tomove the paper down from and off the rolls, as 6. In thus taking up theslack pa per by the take-up roll 5 the former will be thrown forward alittle and will rest upon the curved shelf or the small roll 6, arrangedtherein, whence, especially if the paper be wet, it will be easily drawn'off bythe feed-rolls 10. Each sheet, when cut from the web, is carriedby the belts, as m, down and deposited upon a suitable platform providedfor the purpose, where it is packed. v

In the above description, and as shown in Fig. 1I, I have arranged theframe 3, with its roll 5, als adapted to move freely to and fro in ashoe, as 4, to be pivoted to the frame, as at 50, and clamped or set atany desired inclined position, with the roll 5 resting against the webof paper, so that when the downward movement of the web is stopped atthe bar 9 and the tension ot' the web against the roll is released theframe 3 will follow the loosened paper until the cut is made and therolls 10 commence to draw the lweb down and taut again, and this renewedtension ofthe web moves the frame 3 automatically back into place again5 and in cntting'thin paper the shoe, as 4, may be set at alessinclination than when cutting thick paper, so that in cutting thinpaper the frame 3 will push back easier.

In the above description the frame 3 is partially automatic in itsaction, at leastso far as its movement forward to press the roll 5against the web of paper is concerned; but in Fig. VII is shownmechanism for operating the frame and its roll positively, in which awedge-shaped piece, e, is made upon or attached to the upper side of thestop-bar arm, as 7, with a roll, asf, adapted to revolve in a piece, h,adjusted with an up-and-down movement in guidewa-ys at each end of theframe. A roll, f', is geared to the receiving-roll l so as to revolveconstantly, and when the stop-bar 8 is moved back or away from itsposition against the bar 9 the roll f is permitted to drop; but when thestop-barS is moved in against the bar 9, with the web of paper clampedbetween, the roll f is moved up by the inclined piece e against theframe and the latter clasped between the revolving roll j" and therollf, and the frame 3, with its roll 5, is thereby moved forwardagainst the web as long as the bar 8 remains in that position; but whenthe latter is drawn back and the web released the roll fis permitted todrop, and the frame 3 not then being in contact with the roll f', therenewed tension of the paper moves the frame 3 and its roll 5 back toits position. y

As the knife 14 has a very slight movement in making each cut-say aninch,more orlessit is evident that but comparatively very little slackpaper will accumulate above the rolls 10 or stop-bar 8 while the paperis being cut.

Apiece of some elasticor yielding substance may be inserted in the frontside of the stopbar Sto press against the paper in stopping it, ifdesired.

As the speed of all the working parts of the machine is controlled bythe two cone-drums and 16 and the belt extending around them, it isevident (the speed of the receiving-rolls 1 and 2 always remaining thesame) that the web of the paper will be stopped by the stop bar S andthe sheets severed therefrom with more or less frequency, according asthe conebelt 52 is shifted to different positions along the cone-drumsin one direction or the other, and the sheets be cut of any desiredlength from the web.

Having thus described my invention, what I claim as new is l.' Thecombination, in a paper-cutting machine, of two receiving-rolls, adaptedto re- IOO IIO
